Butterflies
and moths fall under the heading of "live plant pests". Therefore, the
Animal and Plant Health Inspection (APHIS) unit of the United States Department
of Agriculture requires a permit (Form PPQ 526) in order to ship butterfly pupae
across state lines. An application for this permit and much more information can
be found at the link below:

Butterflies Unlimited will not
ship butterfly and moth pupae outside of the state of Texas unless you have a
valid USDA APHIS PPQ 526 on file with us. You must go through this process or
you will be breaking a Federal Law. Since this permit governs the interstate shipping
of live pupae, those exhibits and individuals within the state of Texas can purchase
pupae from Butterflies Unlimited without obtaining a permit. After obtaining
your permit (if outside of Texas) or if you are within the state of Texas, please
see the section Setting Up Orders to purchase pupae from Butterflies
Unlimited.

Many exhibits like to showcase the
butterflies of their particular state. While this is certainly understandable
since the purpose of most exhibits is to make the public more aware of the butterflies
and wildlife in their own area, this practice sometimes limits the species that
are made available to you. To ensure a wider variety of butterflies for your exhibit,
we suggest you list a broader range of species when filling out your permit application.
